DETAILED DESCRIPTION

FIGS. 1-10 show systems or assemblies 100, 100′, and 200 for securing one or more cords C or other elongated, flexible articles in various compact configurations. The cords C can include head phone cords, charging cords for personal electronic devices, such as phones, tablets, laptops, etc. (e.g., Lighting Cables, USB cords, etc.), extension cords, computer cords, computer accessory cords (e.g., for printers, keyboards, scanners etc.), television cords (e.g., HMDI cords, coaxial cables, etc.) or other suitable electric or non-electric cords, wires, cables, etc.

As FIGS. 1-10 indicate, these assemblies 100, 100′, 200 generally include a tail or elastic portion 10 (broadly: an elongate body 10) configured to be wrapped around or positioned about a cord C, e.g., for securing the cord C (or cords C) in various compact configurations. The elastic portion 10 generally includes a substantially flexible material that has a selected elasticity such that the elastic portion 10 can be stretched or otherwise positioned around the cord C (or cords) to engage or press the cord C in various selected compact configurations. The various compact configurations can include different amounts, portions, etc. of the cord C (or cords) folded, coiled, wrapped, etc. The elastic portion 10 can be formed from elastic, flexible and/or stretchable materials, such as elastomers, natural rubbers, polyurethane, polybutadiene, neoprene, silicone, etc., though other suitable plastic, composite, synthetic, etc. materials can be used without departing from the scope of the present disclosure. The elastic portion 10 further has a first end portion 10A and a second end portion 10B.

The assemblies 100, 100′, 200 further include attachment or connection apparatuses 12, 14 attached to the elastic portion 10 at, along, or substantially adjacent to the first and second end portions 10A, 10B as generally indicated in FIGS. 1-10. The attachment apparatuses 12, 14 can include a first attachment apparatus 12 and a second attachment apparatus 14. In some embodiments, portions of the first attachment apparatus 12 and/or the second attachment apparatus 14 can be formed from a rigid material, such as hard rubber, hard plastic, metals, wood, etc., or other suitable rigid plastic, composite, synthetic, etc. materials. The first and/or second attachment apparatuses 12,14 can be configured to be connectable to the cord C for attaching or fixing the assembly 100, 100′, 200 to the cord C. The material forming the elastic portion 10 can be a first material and the material forming the attachment apparatus 12 or 14 can be a second material. The first attachment apparatus 12 and the second attachment apparatus 14 further are connectable together to secure the elastic portion 10 about the cord C when the elastic portion 10 is wrapped or stretched around the cord C.

In use, when it is desired to place the cord C in a compact configuration, the cord C can be at least partially or substantially entirely wrapped, coiled or folded up into the desired compact configuration (e.g., a bundle B) and the elastic portion 10 can be stretched and positioned around the bundle B to hold or secure the cord C in its selected compact configuration. With the elastic portion 10 stretched about the cord C, the first attachment apparatus 12 and the second attachment apparatus 14 can be connected together to secure the elastic portion 10 thereabout (e.g., FIGS. 6 and 10). The elastic portion 10 further can be under tension and compress or engage the cord C in its wrapped configuration. The tension provided along the elastic portion 10 also can press or engage the first attachment apparatus 12 and the second attachment apparatus 14 against one another.

FIGS. 1-6 show an assembly 100 for securing one or more cords C in selected compact configurations according to an exemplary embodiment. As shown in FIGS. 1-6, the first attachment apparatus 12 includes an enlarged portion or connector 102 extending from the first end portion 10A of the elastic portion 10. The connector 102 includes a connector body 104 at least partially extending around and defining a passage or channel 106 and a slot 108 that are configured to receive a portion of the cord C. This passage 106 is generally sized, dimensioned, and/or otherwise configured such that a portion of the cord C can be inserted therethrough to facilitate attachment/connection of the assembly 100 to the cord C, as generally indicated in FIG. 6. In the illustrated embodiment, the slot 108 can be in communication with the passage 106 and can be defined between a first wall 110 and a second wall 112 extending along respective portions of the connector body 104 (FIGS. 1, 3, and 4). In the illustrated embodiment, the assembly 100 can be attached to the cord C by moving (e.g., pressing) the portion of the cord C through the slot 108 to the passage 106 so that the portion of the cord C is engaged by the passage 106 (FIG. 6) (e.g., the cord C can be engaged to tightly enclose or secure the portion of the cord C) such that the assembly 100 is retained with the cord C, e.g., during the use thereof, i.e., charging, listening to music, etc.

In the embodiment shown in FIGS. 1-6, the second attachment apparatus 14 can include a plurality of bulbous portions 114 positioned in a spaced relation along a portion of the elastic portion 10 extending from the second end 10B. Each of the bulbous portions 114 can have a generally spherical shape or any suitable shape (e.g., disk-like shapes, semi-spherical shapes, oblong shapes, etc.). Further, as shown in FIGS. 1-6, the connector 102 can include a recessed portion 120 defined in the connector body 104 and shaped, sized, or otherwise configured to at least partially receive a selected one of the bulbous portions 114. For example, one of the bulbous portions 114 can be engaged against a surface or face of or defined along the recessed portion 120 to secure the elastic portion 10 about one or more cords C (FIG. 6).

In the illustrated embodiment, the connector body 104 further includes prongs 122 substantially adjacent or otherwise along the recessed portion 120. In an exemplary embodiment, the prongs 122 can form part of the recessed portion 120. The prongs 122 thus can define a pair of spaced apart surfaces that can be engaged by the bulbous portion 114. As shown in FIGS. 1-6, the surfaces of the recessed portion 120 and the prongs 122 can have a generally curved or arcuate shape, though other shapes are possible. The prongs 122 further define a slot or gap 124 configured to at least partially engage or contact a portion of the elastic portion 10 to help secure and retain the bulbous portion 114 within or along the recessed portion 120. For example, the prongs 122 can frictionally engage or contact opposing sides of at least a portion of the elastic portion 10 to secure the bulbous portion 114 within or along the recessed portion 120. In the illustrated embodiment, the bulbous portions 114 can be selectively engaged with the recessed portion 120 to allow for selective tightening of the elastic portion 10 about one or more cords C, e.g., to accommodate cords of different sizes and/or various selected/desired folded, coiled, wrapped configurations. In embodiments, the recessed portion can have a different configuration, for example, including one or more notches formed on the connector body. The elastic portion 10, the first attachment apparatus 12 (including the connector 102, the connector body 104, the passage 106, the slot 108, the walls 110, 112, the recessed portion 120, the prongs 122, and/or the gap 124), and/or the second attachment apparatus (including any or all of the bulbous portions 114) could be otherwise shaped, sized, positioned, and/or configured without departing from the disclosure

In the illustrated embodiment, the elastic portion 10 and the bulbous portions 114 can be formed from a first material that is flexible and/or stretchable, such as elastomers, rubber, polyurethane, polybutadiene, neoprene, silicone, etc., though other suitable plastic, composite, synthetic, etc. materials can be used without departing from the scope of the present disclosure. In some embodiments, the bulbous portions 114 can be formed with the remainder of the elastic portion (e.g., can be integral with and/or continuous with the elastic portion 10). In other embodiments, the bulbous portions 114 can be separately formed of the same material or a different material and can be mounted to (e.g., adhered to, welded to, fused to, etc.) the remainder of the elastic portion 10. As shown in FIGS. 4 and 5, the connector 102 can have a first portion 130 and a second portion 132 that cooperate to at least partially form the connector body 104. The first portion 130 can be an extension of the elastic portion 10 (e.g., can be integrally formed with the elastic portion 10). The second portion 132 can be formed from a second material that is more rigid than the first material. For example, the second material can include hard rubber, hard plastic, metallic materials, wood, etc., or other suitable hard plastic, composite, synthetic, etc. materials or combinations thereof. In some embodiments, the second portion 132 can be over-molded with a softer and/or more resilient material, such as elastomers, rubber, polyurethane, polybutadiene, neoprene, silicone, etc. and/or other suitable plastic, composite, synthetic, etc. materials. As shown in FIG. 5, the second portion 132 includes the recessed portion 120 and the prongs 122, and the relative rigidity of the second portion 132 allows a selected one of the bulbous portions 114 to be secured within or along the recessed portion 120 (e.g., under urging or tension of the elastic portion 10) and allows the elastic portion 10 to be inserted and secured in the gap 124. As shown in FIG. 4, a portion of the second portion 132 can be received in an opening in the first portion 130 to form the connector body 104. In one embodiment, the first portion 130 and the second portion 132 can be adhered or otherwise secured together.

In use, the assembly 100 can be connected to a portion of the cord C (e.g., an end portion) by positioning the portion of the cord C between the first end 10A of the elastic portion 10 and a convex curved portion of the connector body 104 and pressing the portion of the cord C through the slot 108 to the passage 106. In one embodiment, the walls 110, 112 of the connector body 104 can be curved to help guide the cord portion into the slot 108. In an exemplary embodiment, at least a portion of the connector body 104 can compress and/or deform as the cord C moves through the slot 108 (e.g., the elastic material can compress and/or deform and/or the second portion 132 can bend) and can return or rebound to its original configuration once the cord C exits the slot 108 to be is positioned in the passage 106 to help retain the cord C in the passage 106. Accordingly, the cord C can be pushed into the connector 102 to quickly and easily attach the assembly 100 and the cord C. The cord C further can be engaged or pulled by a user and moved through the slot 108 to move apart the side portions 110 and 112 to facilitate quick and easy removal or release of the cord C and the assembly 100.

When it is desired to secure the cord C in a selected compact configuration, the cord C can be at least partially or substantially entirely wrapped, coiled, and/or folded to form a bundle B of the cord C (FIG. 6), and the elastic portion 10 can be stretched and/or looped around the bundle B, e.g., in the selected compact configuration of the cord C (FIG. 6). Thereafter, as indicated in FIG. 6, a portion of the elastic portion 10 can be inserted through the gap 124 of the prongs 122 such that a selected one of the bulbous portions 114 is positioned proximate the prongs 122 and the recessed portion 120 (e.g., adjacent the concave portion of the connector body 104 defining the recessed portion). When the elastic portion 10 is released, the tension in the elongated elastic portion 10 compresses or secures the cord in its selected compact configuration and further engages or presses the selected bulbous portion 114 against the recessed portion 120 of the connector 102, such that the elastic portion 10 is securely engaged, compressed, and/or tightly wrapped about the cord C to secure it in the selected compact configuration. That is, in an embodiment, the tension on the elastic portion 10 compresses and secures the cord in its selected compact configuration and further presses the selected bulbous portion 114 of the second attachment apparatus 14 against the connector 102 of the first attachment apparatus 12 to facilitate a substantially secure connection therebetween. In this regard, a first portion of the cord C is engaged with/attached to the first attachment apparatus 12 and a second portion of the cord C is engaged with/attached to the second attachment apparatus 14.

In an exemplary embodiment, the bulbous portion 114 can be selected so that the elastic portion 10 can be stretched when the elastic portion is wrapped over the bundle of the cord C and the selected bulbous portion 114 is engaged with the recessed portion 120 and the resulting tension in the elastic portion 10 can help retain the selected bulbous portion 114 against the surface of the recessed portion 120. For example, for a larger cord C and cord bundle B, the selected bulbous portion 114 can be closer to the end 10B of the elastic portion 10, and for a smaller bundle B, one can select a bulbous portion 114 that is closer to the end 10A of the elastic portion 10.

While the attachment apparatus 14 includes six (6) bulbous portions 114 as shown in FIGS. 1, 2, and 6, any suitable number of bulbous portions 114 could be included (e.g., 1 or more bulbous portions). For example, an alternative assembly 100′ is shown in FIG. 7. In the illustrated embodiment, the alternative assembly 100′ can have an attachment apparatus 14′ with four (4) bulbous portions 114.

FIG. 8 shows an assembly 200 for securing one or more cords C in selected compact configurations according to another embodiment, wherein the first attachment apparatus 12 includes a connector 202 at or substantially adjacent the first end 10A of the elastic portion 10. In the illustrated embodiment, the connector 202 includes a connector body 204 having a hook shape 222 that is curved to define the recessed portion 220 (e.g., a concave curved portion) configured to receive a portion of the elastic portion 10. In one embodiment, a distal end 223 of the hook shape 222 is spaced apart from a remainder of the connector body 204 by a distance, which can be sized so that the elastic portion 10 can slide or snap between the distal end 223 and the remainder of the connector body 204 into a receiving space 225 at least partially defined by the recessed portion 220 and/or the hook shape 222. In the illustrated embodiment, the width of the space 225 under the recessed portion 220 can be smaller than the size of the bulbous portions 114 so that the bulbous portions 114 cannot be easily pulled through the space 225 under the recessed portion 220 when the elastic portion 10 is engaged under the recessed portion 220.

As shown in the schematic cross-section of FIG. 9, the connector body 204 can include an outer portion 230, which can be continuous with the elastic portion 10, and an inner portion 232, which can be a metal strip that is bent into the shape of the connector body 204. In one embodiment, the outer portion 230 can be over-molded on the inner portion 232. The connector body 204 could be otherwise configured without departing from the disclosure. For example, the inner portion 232 could include hard rubber, hard plastic, metallic materials, wood, etc., or other suitable hard plastic, composite, synthetic, etc. materials or combinations thereof.

In use, an end or another portion of the cord C can be engaged with the passage 106, the remainder of the cord C can be formed into a bundle B, and the elastic portion 10 can be at least partially wrapped around the bundle B similarly to the process described above with respect to the assembly 100 shown in FIGS. 1-6. The attachment apparatus 14′ can be engaged with the hook shape 222 by pulling (e.g., stretching) the elastic portion 10 around the bundle B of the cord C and inserting a portion of the elastic portion 10 past the distal end 223 of the hook shape 222 and into the space 225. In one embodiment, the tension in the elastic portion 10 can pull an adjacent one of the bulbous portions 114 against a side of the hook shape 222 so that the attachment apparatus 14′ is retained in engagement with the hook shape 222 and the elastic portion 10 retains the cord bundle B in engagement with the assembly 200. In this regard, a first portion of the cord C is engaged with/attached to the first attachment apparatus 12 and a second portion of the cord C is engaged with/attached to the second attachment apparatus 14.
